A bicycle, often called a bike or cycle, is a human-powered, pedal-driven, single-track vehicle, having two wheels attached to a frame, one behind the other. A bicycle rider is called a cyclist, or bicyclist. Bicycles were introduced in the 19th century in Europe and, as of 2003, more than a billion have been produced worldwide, twice as many as the number of automobiles that have been produced. They are the principal means of transportation in many regions. They also provide a popular form of recreation, and have been adapted for use as children’s toys, general fitness, military and police applications, courier services, and bicycle racing. The basic shape and configuration of a typical upright, or safety bicycle, has changed little since the first chain-driven model was developed around 1885. But many details have been improved, especially since the advent of modern materials and computer-aided design. These have allowed for a proliferation of specialized designs for many types of cycling. The bicycle’s invention has had an enormous effect on society, both in terms of culture and of advancing modern industrial methods. Several components that eventually played a key role in the development of the automobile were initially invented for use in the bicycle, including ball bearings, pneumatic tires, chain-driven sprockets, and tension-spoked wheels. From the beginning and still today, bicycles have been and are employed for many uses. In a utilitarian way, bicycles are used for transportation, bicycle commuting, and utility cycling. It can be used as a ‘work horse’, used by mail carriers, paramedics, police, messengers, and general delivery services. The bicycle is also used for recreational purposes, such as bicycle touring, mountain biking, physical fitness, and play. Bicycle competition includes racing, BMX racing, track racing, criterium, roller racing, sportive and time trials. Major multi-stage professional events are the Tour of California, Giro d’Italia, the Tour de France, the Vuelta a España, and the Volta a Portugal. Bicycle use can be seen by the police for surveillance, while the military uses bicycles for scouting, troop movement, supply of provisions, and patrol. Bikes can be used for entertainment and pleasure, such as in organized mass rides, artistic cycling and freestyle BMX.

Rice (Malay: nasi) was and still is the most important staple food in Malaysia. According to Indonesian-born food and cookery writer Sri Owen, there is some evidence for rice cultivation found in the state of Sarawak in Malaysian Borneo dated 2300 BC, and about 900 years of history for the state of Kelantan in West Malaysia. Today Malaysia produces about seventy percent of the amount of rice it needs to support itself, and the rest is imported. This is a matter of policy as the government believes that national resources can be used more profitably instead of attempting to achieve self-sufficiency with rice production; the prevalent attitude is that revenue generated from its industries enables the country to import up to half the rice it needs. Nevertheless, the government is fully committed and involved in planning, allocating resources and managing subsidies for the rice farming industry. The state of Kedah is considered the “rice bowl” (Malay: jelapang padi) of the country, accounting for about half of Malaysia’s total production of rice. Plain steamed white rice, to be served with side dishes of meat or vegetables, is typically prepared with an electric rice cooker at home. Some households and food establishments prefer to cook rice on a stove top with the absorption method or the rapid-boil method. Compressed rice, called nasi himpit, is another method of preparing and cooking rice: the rice is wrapped with fronds or leaves and compressed into the form of a cylinder, which is then cooked by boiling. The rice would compress and merge during the cooking process. Compressed rice is usually eaten cold with some sort of gravy, although it may be served warm in a broth or soup. A notable variant of compressed rice prepared by the Bugis community is burasak: rice is precooked with coconut milk before it is wrapped in banana leaves and steamed until fully cooked. Besides the ubiquitous white rice, there are different types of locally grown and imported rice available in the market, and each type has a specific cooking method to bring out optimal results. Glutinous rice (Malay: pulut) is one example: because of its low amylose and high amylopectin content which results in a sticky texture after cooking, glutinous rice is prepared with different measurements and techniques and is not a suitable substitute for normal rice or vice versa. It is typically used for making snacks and desserts, but glutinous rice is also prepared as a savoury staple by indigenous peoples like the Orang Asli as well as the Dayak people of Borneo. Lemang is glutinous rice roasted in a hollowed bamboo tube, and is prepared for festive occasions like Ari Gawai, Hari Raya Aidilfitri, and Hari Raya Aidiladha.

Irrigation is the artificial application of water to the land or soil. It is used to assist in the growing of agricultural crops, maintenance of landscapes, and revegetation of disturbed soils in dry areas and during periods of inadequate rainfall. Additionally, irrigation also has a few other uses in crop production, which include protecting plants against frost, suppressing weed growth in grain fields and preventing soil consolidation. In contrast, agriculture that relies only on direct rainfall is referred to as rain-fed or dryland farming. Irrigation is often studied together with drainage, which is the natural or artificial removal of surface and sub-surface water from a given area. Archaeological investigation has identified evidence of irrigation where the natural rainfall was insufficient to support crops. Perennial irrigation was practiced in the Mesopotamian plain whereby crops were regularly watered throughout the growing season by coaxing water through a matrix of small channels formed in the field. Ancient Egyptians practiced Basin irrigation using the flooding of the Nile to inundate land plots which had been surrounded by dykes. The flood water was held until the fertile sediment had settled before the surplus was returned to the watercourse. There is evidence of the ancient Egyptian pharaoh Amenemhet III in the twelfth dynasty (about 1800 BCE) using the natural lake of the Faiyum Oasis as a reservoir to store surpluses of water for use during the dry seasons, the lake swelled annually from flooding of the Nile. In sub-Saharan Africa irrigation reached the Niger River region cultures and civilizations by the first or second millennium BCE and was based on wet season flooding and water harvesting. Terrace irrigation is evidenced in pre-Columbian America, early Syria, India, and China. In the Zana Valley of the Andes Mountains in Peru, archaeologists found remains of three irrigation canals radiocarbon dated from the 4th millennium BCE, the 3rd millennium BCE and the 9th century CE. These canals are the earliest record of irrigation in the New World. Traces of a canal possibly dating from the 5th millennium BCE were found under the 4th millennium canal. Sophisticated irrigation and storage systems were developed by the Indus Valley Civilization in present-day Pakistan and North India, including the reservoirs at Girnar in 3000 BCE and an early canal irrigation system from circa 2600 BCE. Large scale agriculture was practiced and an extensive network of canals was used for the purpose of irrigation. The irrigation works of ancient Sri Lanka, the earliest dating from about 300 BCE, in the reign of King Pandukabhaya and under continuous development for the next thousand years, were one of the most complex irrigation systems of the ancient world. In addition to underground canals, the Sinhalese were the first to build completely artificial reservoirs to store water. Due to their engineering superiority in this sector, they were often called ‘masters of irrigation’. [By whom?] Most of these irrigation systems still exist undamaged up to now, in Anuradhapura and Polonnaruwa, because of the advanced and precise engineering. The system was extensively restored and further extended during the reign of King Parakrama Bahu (1153–1186 CE).

Grasses, or more technically graminoids, are monocotyledonous, usually herbaceous plants with narrow leaves growing from the base. They include the “true grasses”, of the family Poaceae (also called Gramineae), as well as the sedges (Cyperaceae) and the rushes (Juncaceae). The true grasses include cereals, bamboo and the grasses of lawns (turf) and grassland. Sedges include many wild marsh and grassland plants, and some cultivated ones such as water chestnut (Eleocharis dulcis) and papyrus sedge (Cyperus papyrus). Uses for graminoids include food (as grain, sprouted grain, shoots or rhizomes), drink (beer, whisky, vodka), pasture for livestock, thatch, paper, fuel, clothing, insulation, construction, sports turf, basket weaving and many others. Graminoids include some of the most versatile plant life-forms. They became widespread toward the end of the Cretaceous period, and fossilized dinosaur dung (coprolites) have been found containing phytoliths of a variety that include grasses that are related to modern rice and bamboo. Grasses have adapted to conditions in lush rain forests, dry deserts, cold mountains and even intertidal habitats, and are now the most widespread plant type; grass is a valuable source of food and energy for all sorts of wildlife and organics. Graminoids are the dominant vegetation in many habitats, including grassland, salt-marsh, reedswamp and steppes. They also occur as a smaller part of the vegetation in almost every other terrestrial habitat. Many types of animals eat grass as their main source of food, and are called graminivores – these include cattle, sheep, horses, rabbits and many invertebrates, such as grasshoppers and the caterpillars of many brown butterflies. Grasses are also eaten by omnivorous or even occasionally by primarily carnivorous animals. Grasses are unusual in that the meristem is located near the bottom of the plant, hence can quickly recover from cropping at the top. In the study of ecological communities, herbaceous plants are divided into graminoids and forbs, which are herbaceous dicotyledons, mostly with broad leaves.

Fishing is the activity of catching fish. It is an ancient practice dating back at least 40,000 years. Since the 16th century fishing vessels have been able to cross oceans in pursuit of fish and since the 19th century it has been possible to use larger vessels and in some cases process the fish on board. Fish are normally caught in the wild. Techniques for catching fish include hand gathering, spearing, and netting, angling and trapping. The term fishing may be applied to catching other aquatic animals such as shellfish, cephalopods, crustaceans, and echinoderms. The term is not usually applied to catching aquatic mammals, such as whales, where the term whaling is more appropriate, or to farmed fish. In addition to providing food, modern fishing is also a recreational sport. Fishing is an ancient practice that dates back at least to the Upper Paleolithic period which began about 40,000 years ago. Isotopic analysis of the skeletal remains of Tianyuan man, a 40,000 year old modern human from eastern Asia, has shown that he regularly consumed freshwater fish. Archaeological features such as shell mildens, discarded fish bones and cave paintings show that sea foods were important for survival and consumed in significant quantities. During this period, most people lived a hunter-gatherer lifestyle and were, of necessity, constantly on the move. However, where there are early examples of permanent settlements (though not necessarily permanently occupied) such as those at Lepenski Vir, they are almost always associated with fishing as a major source of food. The Neolithic culture and technology spread worldwide between 4,000 and 8,000 years ago. With the new technologies of farming and pottery came basic forms of the main fishing methods that are still used today. Oppian of Corycus, a Greek author wrote a major treatise on sea fishing, the Halieulica or Halieutika, composed between 177 and 180. This is the earliest such work to have survived intact to the modern day. Oppian describes various means of fishing including the use of nets cast from boats, scoop nets held open by a hoop, spears and tridents, and various traps “which work while their masters sleep”. Oppian’s description of fishing with a “motionless” net is also very interesting: The fishers set up very light nets of buoyant flax and wheel in a circle round about while they violently strike the surface of the sea with their oars and make a din with sweeping blow of poles. At the flashing of the swift oars and the noise the fish bound in terror and rush into the bosom of the net which stands at rest, thinking it to be a shelter: foolish fishes which, frightened by a noise, enter the gates of doom. Then the fishers on either side hasten with the ropes to draw the net ashore. In traditional Chinese history, history begins with three semi-mystical and legendary individuals who taught the Chinese the arts of civilization around 2800–2600 BC: of these Fu Hsi was reputed to be the inventor of writing, hunting, trapping, and fishing.
